In a new study, researchers say they believe that, for the first time, there is evidence to show that three doses of vaccine increase antibody levels against SARS-CoV-2 -- the virus that causes COVID 19 -- more than the standard two-dose regimen for people who have received solid organ transplants.

A new therapy prompts immune defense cells to swallow misshapen proteins, amyloid beta plaques and tau tangles, whose buildup is known to kill nearby brain cells as part of Alzheimer's disease, a new study shows.

Researchers have created what could be a key building block for assembling a synthetic kidney. They describe how they generate rudimentary kidney structures, known as organoids, that resemble the collecting duct system that helps maintain the body's fluid and pH balance by concentrating and transporting urine. The organoids provide a way to study kidney disease that could lead to new treatments and regenerative approaches for patients.

Artificial intelligence (AI) may offer a way to accurately determine that a person is not infected with COVID-19. An international retrospective study finds that infection with SARS-CoV-2, the virus that causes COVID-19, creates subtle electrical changes in the heart. An AI-enhanced EKG can detect these changes and potentially be used as a rapid, reliable COVID-19 screening test to rule out COVID-19 infection.

In a new study, the researchers found that the common respiratory virus jump-starts the activity of interferon-stimulated genes, early-response molecules in the immune system which can halt replication of the SARS-CoV-2 virus within airway tissues infected with the cold.

What exactly triggers a sneeze? A team has identified, in mice, specific cells and proteins that control the sneeze reflex. Better understanding of what causes us to sneeze -- specifically how neurons behave in response to allergens and viruses -- may point to treatments capable of slowing the spread of infectious respiratory diseases.

New research shows pregnant women exposed to higher levels of air pollution have babies who grow unusually fast in the first months after birth, putting on excess fat that may put them at risk of obesity and related diseases later in life.

Researchers have succeeded for the first time in demonstrating the role of hypothalamic astrocytes in obesity-related hypertension. In addition, they showed that the hormone leptin is involved in the increase of blood vessels in the hypothalamus of obese mice, contributing of hypertension.

Researchers have identified two subgroups of adolescents who self-harm and have shown that it is possible to predict those individuals at greatest risk almost a decade before they begin self-harming.

Stem cell biologist have discovered that the pituitary gland in mice ages as the result of an age-related form of chronic inflammation. It may be possible to slow down this process or even partially repair it.
